The present invention relates to devices and methods for providing controlled environments for surgical procedures, as well as transplantation and wound healing. In particular, one embodiment of the present invention provides devices and methods to provide an anaerobic environment for incision sites. In other embodiments, the present invention provides devices and methods to maintain anaerobic conditions during the collection, transport, and implantation of organs, tissues, cells, and other transplant material. In further embodiments, the present invention provides devices and methods for the production and maintenance of an anaerobic environment surrounding sites of trauma or tissue injury. In particular, the present invention provides devices and methods which allow the operator to strictly control the environment for surgical procedures, transplantation and wound healing, etc. Thus, the present invention also finds use in specialized settings where hyperoxic conditions are desireable.

What is claimed is: 1. A method comprising: a) providing a device for maintaining an area in an isolated environment, said device comprising an enclosure for separating said area from an atmosphere ambient to said device, a means for evacuating said isolated environment, a means for refilling said
What is claimed is: 1. A method comprising: a) providing a device for maintaining an area in an isolated environment, said device comprising an enclosure for separating said area from an atmosphere ambient to said device, a means for evacuating said isolated environment, a means for refilling said isolated environment, and at least one access port, wherein said area is chosen from a surgical field and an injured area; and b) positioning the device over said area and releasably attaching said device to a patient's skin surrounding said area. 2. The method of claim 1, wherein said injured area is selected from the group consisting of burns, lesions, and broken bones. 3. The method of claim 1, wherein said at least one access port is suitable for admission of at least one surgical means selected from the group consisting of surgical instruments, robotics, sensors, and human hands. 4. The method of claim 1, further comprising step c) evacuating any gas within said isolated environment by using said means for evacuating. 5. The method of claim 4, further comprising step d) introducing sterile gas into said isolated environment by using said means for refilling. 6. The method of claim 5, wherein said means for refilling produces an environment with reduced oxygen tension. 7. The method of claim 5, wherein said means for refilling produces an environment with increased oxygen tension. 8. The method of claim 5, wherein said sterile gas is chosen from nitrogen, argon and a mixture thereof. 9. The method of claim 1, wherein said isolated environment is essentially pathogen-free. 10. A method comprising: a) providing a device for maintaining an area in an isolated environment, said device comprising an enclosure for separating said area from an atmosphere ambient to said device, a means for filling said isolated environment, and at least one access port, wherein said area is chosen from a surgical field and an injured area; and b) positioning the device over said area and releasably attaching said device to a patient's skin surrounding said area. 11. The method of claim 10, wherein said means for filling produces an environment with reduced oxygen tension. 12. The method of claim 10, wherein said means for filling produces an environment with an increased oxygen tension. 13. A method comprising: a) providing a device for maintaining and transporting transplant material in an isolated environment, said device comprising an enclosure for separating said transplant material from an atmosphere ambient to said device, a means for evacuating said isolated environment, a means for refilling said isolated environment, and an airlock for attaching said device to a controlled surgery environment, wherein the oxygen tension of said isolated environment is controllable; b) placing said transplant material in said device; and c) transporting said transplant material in said device to a transplant operation site. 14. The method of claim 13, wherein said means for evacuating comprises means for oxygen release and retention of a heavy gas within said isolated environment. 15. The method of claim 13, wherein said means for evacuating produces an environment with reduced oxygen tension. 16. The method of claim 13, wherein said means for refilling produces an environment with reduced oxygen tension. 17. The method of claim 13, wherein said means for refilling produces an environment with an increased oxygen tension. 18. The method of claim 13, wherein said isolated environment is essentially pathogen-free. 19. The method of claim 13, wherein said transplant material is selected from the group consisting of organs, tissues, cells, and artificial materials.
